Self-Loading What slugs in the Rattler .30?

[yusabo123]

What slugs (size, weight and speed) are you using in your Western Rattler .30?. Thanks!

Western Airguns Rattler Full/Semi Auto .30 *2!!!!!!​

I own two .30 Sidewinder high-energy versions. I noticed that the new barrel I received has 10 lines, and the rifling is thick and thin. Is this a new barrel? I want to know the bullet data he uses.​

It's been a few weeks now and no-one with experience with the Rattler 30 cal and slugs have responded. I'm interested to see this data also. How has your heavy slug testing gone this far?

As far as the barrels go, from what I understand, Sub-Moa is now the barrel manufacturer for Western, so one may have a new barrel made by them.

Thanks for the response. There's a few questions with regairs to the platform and such... What is the max fps are you are able to be pushing them to, with the power wheel maxed out and on what plenum pressure? And what is the longest slug the magazine will accept? Have you tried any long rebated boat tail slugs?
